Ocean Surface Current Measurements with a Single-Station, Doppler/Spaced-Antenna Radar

摘要

The authors conducted a preliminary experiment to determine the feasibility of using one radar to measure the two-dimensional ocean surface current. The Doppler method was used to measure the radial component and the Spaced Antenna (SA) method was used to measure the transverse component of the current. This dual method produced current measurements that showed consistency over range and time, demonstrating potential for the technique. However, the experiment also raised some questions. On occasions, the SA method seemed to be very sensitive to noise, producing apparently erroneous results. Therefore, the authors have planned a more definitive experiment with improved radar antennas, with improved data acquisition, and with independent current observations for comparisons.
